Description
- The present invention relates to packaging machines, particularly the invention refers to a device for separating, transferring and discharging containers, principally flexible containers for pharmaceutical use, for instance strips of monodose containers or bag for parenteral solutions.
- The known separating devices pick the single containers, for instance from a feeding store, by using mobile gripping means or pushers, by which the separating devices discharge said containers into following transferring devices.
- In case of flexible containers, these transferring devices usually include support elements, the so-called "holders", with seats or shaped pits, in which the containers are housed.
- The instability of these latter, in fact, makes necessary the use of said support elements, which are suitable to maintain the containers in the correct position and in the requested orientation, during their transfer.
- Blocks of plastic material, for instance polyethylene or other synthetic resin, in which the seats for the containers are carried out, usually constitute the support elements.
- Said support elements are fixedly or removably connected to conveyor, for instance belts or chains, which move with continuous or alternate motion.
- Furthermore there are known transferring devices having mobile gripping means, for instance grippers with jaws or elements with opposed half shells, controlled by suitable actuators and usually connected to working carousels or rotating drums. Said kind of devices are used for transferring the containers to working planes at different heights or to change their orientation, for instance by rotating or turning upside-down said containers.
- The known discharging devices are similar with the separating devices and have mobile gripping means or pusher means, fit to extract the containers from the related seats of the support elements and to transfer the container to following devices or operational stations.
- The main drawback of the known devices for separating, transferring and discharging containers consists in the use of mobile gripping means of the containers that usually require a complex mechanics for the motion, with consequent high costs for the design and the manufacturing.
- Other drawback consists in the configuration of the mobile gripping means, which do not allow an immediate accessibility to the containers, during the different phases of the operational process or in case of emergency stop of the device.
- Further drawback of the known devices consists in that the support elements for the container transfer are usually bulky and heavy and cause a substantial increase of the machine inertia, with consequent reduction of the dynamic performances of the machine in terms of accelerations and achievable maximum speed; at the same time said support elements with their dimensions limit the movement of the container through the machine.
- The main object of the present invention is to propose a device for separating, transferring and discharging containers having mobile gripping means very simple to carried out, light and having small dimensions.
- Further object is to propose a device fit to utilize the container flexibility in the separating, transferring and discharging operations all along the operational stations of the machine. Other object is to propose a simple and economic device that does not require a machine mechanics complex and expensive. Further object is to propose a device whose gripping and transfer means allow an easy and immediate accessibility to the containers, in every motion phase.
- The above-mentioned objects are achieved according to the content of the claims.
- The characteristics of the present invention are underlined in the following with particular reference to attached drawings, in which:
- figure 1 shows a schematic front view of the device object of the present invention;
- figure 2 shows a enlarged and partial schematic front view of the figure 1 device;
- figures 3A-3E show partial front views of the figure 1 device respectively in correspondence of engagement, moving, gripping, removal and picking conditions of each container;
- figure 4 shows a partial side view of the figure 1 device;
- figures 5A and 5B show partial front views of the figure 1 device respectively in correspondence of a moving condition and a gripping and discharging condition of each container;
- figures 6A-6D show partial and schematic front view of the figure 1 device, respectively in correspondence of transferring, hooking, discharging and disengagement conditions of each container.
- With reference to figure 1,
numeral 1 indicates the separating, transferring and discharging device, which includes aframe 10, separating means 5, transfer means 6 and stop means 7 offlexible containers 101. - For instance, the
device 1 is fit in a machine for moving, filling and packaging containers and therefore has afirst conveyor 4 of the containers positioned upstream said device and asecond conveyor 8 downstream thedevice 1. - The separating means 5, shown in figure 2, include pusher means, upper 501 and lower 502, slidably connected to related columns, upper 503 and lower 504, connected to the
frame 10 by means of asupport arm 508. - Each pusher mean has at the contact end with the container a
seat 515 fit to match thesingle container 101 or the couple of containers in case of two packaging lines, in such a way to allow the translation of these latter, stopping at the same time theremaining containers 101 laying in thefirst conveyor 4. - Shifting means 520 translate at the same time the pusher means, from an engagement condition A with a
related container 101, to a shift condition B in which eachcontainer 101 is translated downwards to be grabbed by the transfer means 6, to a removal condition S in which said pusher means are parted to disengage the container and to allow its passage to the transfer means 6. - The
shifting means 520 are constituted by two rotating shafts inside thesupport arm 508 and are connected to the machine motor, said shafts move the pusher means, respectively lower 502 and upper 501, by means ofcrank arms rods support arm 508 also supports the fixedhorizontal abutment 505 of the container. - The shifting means 520 include disengagement elastic means, not shown, which disengage each pusher means, upper 501 and lower 502, from the motor in case the pusher mean by translating counters a resistant force higher than a predetermined value: for instance, in case of containers jamming or blocking in the separating means 5, so preserving the integrity of this latter.
- With reference to figures 4, 5A and 5B, the transfer means 6 include a
support frame 610 hinged to the machine and supporting belt transfer means 620, to which gripping means 608 of thecontainers 101 are connected. - The
support frame 610 includes an middle swingingshaft 601 hinged to ahorizontal support 604 connected to theframe 10 and rotated with a pendulum movement, between a picking and discharging condition P and a vertical moving condition T, as shown respectively in the figures 5B and 5A. - The transfer means 6 include motorized rotating
shaft 602, parallel to the swingingshaft 601, which is rotated by transmission means 605 and which has toothedpulleys 606 fixed to his ends. At the lower portion of the frame there is idle rotatingshaft 603, parallel to the swingingshaft 601 as well and having fixed to its ends toothedpulleys 606. The belt transfer means 620 are constituted, for instance, by thepulleys 606 and a related couple ofbelts 607, which are rigidly connected by equally spaced crosspieces 609.Sliding blocks 612 guarantee the correct alignment of thebelts 607. - The gripping means 608 include elements connected to crosspieces 609, having
rigid tine seats 611 for picking thecontainers 101 in correspondence of their flexible portions. In alternative, saidtines 611 can be flexible for picking thecontainers 101 in correspondence of rigid portions of these latter. - With reference to figures from 6A to 6D, the stop means 7 are constituted by a
stop 702 operated bydriving means 700, constituted for instance by ahub 701, inside which there is fit ashaft 705, connected to alever 704, linked to the device motor. Theshaft 705 support thestop 702, constituted for instance by a transversal rod, throughpivots 703 longitudinally sliding in respective housing of saidshaft 705, for allowing the adjustment of the stop means according to the container dimensions. - The operation of the separating, transferring and discharging device provides that the separating means 5, in the engagement condition A, keep in position the
container 101, not supported anymore by thebars 401 of thefirst conveyor 4, by the pusher means, upper 501 and lower 502, which fit the container into thecorresponding seats 515. - The synchronous translation of the pusher means downwards cause the removal of a single container, or of a couple of containers, and its shifting in the underlying position, in the shifting condition B.
- The container picking is made by virtue of the rotation, or swinging, of the transfer means 6 which moving from the vertical moving condition T to the picking and discharging condition P, guide the gripping means 608 to stop the containers, supported by the pusher means 501 and 502 and by the fixed
horizontal abutment 505. More precisely said oscillation cause the insertion of a flexible container portion inside the seat defined by twotines 611 of themeans 608. Said insertion is possible by using the container elasticity and the flexibility, as in the case of the monodose strips in which a single container is forced between thetines 611. - A variant provides that the gripping means 608 are flexible and elastic and therefore fit to grab the container rigid portion, for instance bag containers for medical products. After the picking of each
container 101 by the gripping means 608, the pusher means, upper 501 and lower 502, are disengaged in a removal condition S by means of their mutual withdrawal, that is by translating respectively upwards and downwards, to allow the container transfer from the separating means 5 to the transfer means 6. The transfer is carried out through the rotation of the transfer means 6, which move from the picking and discharging condition P to the vertical moving condition T. After that, the pusher means move back in the engagement condition A, to receive the followingcontainers 101. - The transfer means 6 in the vertical moving condition T, as shown in figure 5A, transfer the
containers 101, connected to the gripping means 608 of the belt transfer means 620, from separating means 5 to thesecond conveyor 8. During the shifting of thecontainers 101 on the rising branch of the transfer means 6, the containers are turned over, in virtue of their discharge in correspondence of the descending branch of said transferring means. - With reference to figures from 6A to 6D, the discharge of the
containers 101 to thesecond conveyor 8 from the transfer means 6, is carried out by the rotation of these latter, which rotate in the picking and discharging condition P, in such a way to block acontainer 101 or a couple ofcontainers 101, in picking means 80 of thesecond conveyor 8. - The intervention of the stop means 7, carried out by inserting the
stop 702 in a hooking condition F, cause the container block on the picking means 80. When the transfer means 6 rotate, coming back in the vertical moving condition T, thecontainers 101 remain connected to the picking means 80. The disconnection of thestop 702 from the containers, in a disengagement condition M, allows these latter to be moved by thesecond conveyor 8. - The separating, transferring and discharging
device 1 is completely controlled by electronic calculation and control means fit to check the phase coincidence between the functional elements, particularly the separating means 5, the transfer means 6 and the stop means 7. - The main advantage of the present invention is to provide a separating, transferring, discharging device having mobile picking means very simple to carried out, light and having small dimensions.
- Further advantage is that to provide a device fit to use the container flexibility in the separating, transferring, discharging operations. Other advantage is that to provide a simple and economic device that does not require a complex and expensive mechanic.
- Further advantage consists in providing a device whose picking and transfer means allow an easy and immediate accessibility to the containers, during their shifting.
